Answer

**Step-by-Step Solution:**

1. **Understanding Copper-T**: Copper-T is an intrauterine device (IUD) that releases copper ions. It is a form of contraception used to prevent pregnancy.

2. **Function of Copper-T**: The primary function of Copper-T is to prevent fertilization. It does this by creating an environment in the uterus that is hostile to sperm.

3. **Mechanism of Action**:
- **Increased Phagocytosis**: Copper ions increase the phagocytosis of sperm by immune cells in the uterus, which helps to eliminate sperm.
- **Suppression of Sperm Motility**: Copper-T also affects the motility of sperm, making it difficult for them to reach and fertilize an egg.
- **Prevention of Fertilization**: By creating these conditions, Copper-T effectively inhibits the fertilization process.

4. **Duration of Effectiveness**: Copper-T can remain effective for about 10 years once inserted into the uterus.

5. **Conclusion**: Therefore, the main function of Copper-T is to stop fertilization, making it an effective contraceptive method.

**Final Answer**: The function of Copper-T is to stop fertilization.
